WATERlNG-TROUGH FOR STOCK.

SPECIFICATION forming part of Letters Patent No. 649,436, dated May 15,1900.

Application filed February 12, 1900. Serial No. 4,980. (No model.)

To ctZZ whom it may concern:

Be it known that I, DANIEL B. COOPER, a citizen of the United States,residing at Lebanon, in the county of Smith and State of Kansas, haveinvented certain new and useful Improvements in lVatering=Troughs forStock; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to apparatus for antomatically replenishing thetrough of stockwatering mechanism with water as the same is consumed,whereby a predetermined level of the Water in the trough is maintainedat all times. The valve mechanism is so constructed as to be used inconnection with any style of trough located in any position and can beremoved for inspection and repair and is independent of the trough inwhich it is placed.

The improvement consists of the novel features, details of construction,and combina tion of the parts, which hereinafter will be more fullydescribed and claimed and which are shown in the annexed drawings,inWhich Figure 1 is a sectional detail of the trough, showing the valvemechanism in position and connected with the supply-tank and reservoir.Fig. 2 is a perspective View of the valve mechanism. Fig. 3 is avertical central section thereof.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The trough 1 may be of any size, capacity, and form and is subdivided bya vertical partition 2 into compartments 3 and 4, which are incommunication by means of openings 5, formed in the partition 2. Thevalve mechanism is located in the compartment 4, and the compartment 3is utilized for drinking purposes. A valve 6 is loosely attached at itsupper end to the side of the partition 2, facing the compartment 3, andextends over the openings 5 to within a short distance of the bottom ofthe trough and is designed to prevent dirt and foreign matter passingfrom the compartment 3 into the compartment 4. WVhen the level of thewater in the compartment 3 becomes lower than the level of the I waterin the compartment 4, the valve 6 will move by reason of the superiorpressure of the water in the compartment 4 and uncover the openings 5and permit an equalization of the water-level in both compartments.

The valve mechanism for regulating the supply of water to the troughconsists of a casing 7 of box form, having openings in its top and oneside, a valve 8, applied to the vertical. side, having adischarge-opening and constructed to move inward, a bell-crank 1ever 9,fulcrumed to a block 10, secured to the side of the casing having thedischarge-opening, and a float 11, connected with the outer end of thehorizontal arm of the lever 9. The vertical arm of the lever 9 isconnected by a link 12 with the valve 8, and a rod 13 connects the outerend of the lever 9 with the float 10 and is capable of having itseffective length varied to position the float to correspond with thepredetermined level of water in the tank. The position of the float maybe changed by having it adjustably connected with the rod 13, or thelatter may be composed of sections adj ustably connected. The block 10is secured against the outer side of the Wall of the valve-casing 7 bythe same fastening employed to secure the valve 8 against the innerside, and the lower end of the block is made rounding and is formed witha vertical groove or slot to receive the elbow portion of the lever 9,which is pivoted thereto. The supply-pipe 14 connects with the openingin the top of the casing 7 and leads from the tank or reservoir 15,which contains the water for replenishing the trough as the latter isemptied.

The valve mechanism is Wholly devoid of attachment of any kind to thetrough and can be removed and placed in position at will, therebyfacilitating inspection and the making of repairs when the latter becomenecessary. Aside from this the mechanism can be sold independently ofthe trough and can be placed in position by the average person withoutthe use of tools and can be readily repaired when required.

When the parts are assembled, as shown in Fig. 1, and the water in thetrough reaches the required level, the float 11 is buoyed upward andautomatically closes the valve 8,

thereby shutting off the supply of water. When the level of the waterlowers, the float correspondingly descends and exerting a downwardpressure upon the rod 13 and outer end of the lever 9 forcibly opens thevalve 8 against the head or pressure of supply, thereby permitting theWater to pass from the tank or reservoir 15 into the compartment 4: ofthe trough 1 and from said compartment into the drinking compartment 3until the water reaches the required level, when the supply will againbe cut ofi by the ascent of the float. Having thus described theinvention, What is claimed as new is A valve echanism for stock wateringtroughs, co rising a casing of approximately box form having a sidedischarge-opening and an inlet, an inwardly-opening valve applied to theinner face of the wall having the discharge opening, a block secured tothe outer face of the said side by the same means employed for securingthe valve in place, a 1
